To all whom it may concern.-

Be it known that I, .Pai-RICK BROWN, of in the county pf Philadelphia and State of Pennsylvania` have invented a new and useful improvement in Swing and of' which the followexact description. ention is to produce a either two pieces of ing is a. full, clear, and

The object of Amy inv pipe-joint for uniting pippe without elbow terminations or two pieces of pipe either or both of which have an elbow termination and to permit of either or both of said pipes freely contracting or expanding in direction of their length and of axially rotating without strain upon the joint and tiines,as well ot connected The invention, which is applicableto both steam, water, oil, and other pipes, consists in a novelconstruction of pipejoint,substau tially as hereinafter described, and more para ticularly pointed out in the claim,.whe'reby the above-nained reslts are very perfectly attained, great convenience is afforded in adjusting the pipes,-and breakage of them by expansion and contraction is prevented.

Reference is to be had to the accompanying drawings, forming a part of this specification, in'which similar'letters of reference indicate corresponding parts in all the gures.

Figure 1 represents a longitndinalview of a pipe connection as applied to a steam-boiler he end of -the one pipe ed joint applied'. Fig. 2 is a longitudinal view oftw'o4 pieces4 of` pipe, with elbow at the end of each, also with the joint applied. Fig ii's an exterior longitudinal view ot 'one piece of pipe, in part, with another length of pipe, in part, in section,as also the joint-piece or coupling uniting said pipes;"Fig. LvL a longitudinal section of all the parts or-piecesshoivn in Fig. 3." Fig. 5 is a transverse section upon the line 5 5 in Fig. 3, looking in drectiou ot' the arrow az. Fig. 6 is a rear View of a washer used in llie joint, and Fig. 7 a transverse sccand with my improv `tion of the saine upon the line 7 7 in Fig. (i.

Serial No. 386.658. (No model.) h I I steam-boiler, and A apipe having an elbow b at its outer end and adapted to connect at orcoiipling connection C, embodyingv myin expansion or contraction of the pipe'A and for swinging or turningA tlaxially to change the position of the elbow infamy-required ilirection, butmwfhich is here' simply shown by full and dotted' lines in reverse positions.l Iii" Fig. 2 of the drawings the pipes A A are both supposed to be capable ot' automatic l0ngitudinal adjustment or contraction and expan'sion by means of the joint or coupling connection Gat their adjacent ends' and ot beingaxially turned,as-requircd,to change the position of thc elbows b at their-opposite ends. Y In Figs. 3 and -4 a like'const-ruction of the joint is shown for connecting two straight pipes A1A". In allot these figures thepipes A A may be of any desired length, or any number of theinmay be similarly joinedtogether, and they may run in any required direction and each connected series of pipes be ot' the same interioi` diameter oi; bore.

The joint C, connecting the'ppesA A', is made as follows: The pipe A is constructed with an externally-projecting circular fiange c at its connecting end, which `iange is free as the pipe expands or contracts to move in or out of a circular enlarged box partor chamber d at the connectingend of the ad-v jacent pipe A, and also to axially rotate therein for the purpose' hereinhefore named or whenever required; or the two pipes AA will by this fit of them, one within vthe other, he tree to longitudinally expand`orcontract, and either or lboth ot them may be an ially rotated to swing or turn theelbow Ql, el: bows b at the outer end or, .ends yof them, it so provided,in any required` direction, and Where there are elbows on both pipes to turn the saine in reverse directions, it desiredas shown in Fig. 2,01' it inight -be in the-1 saine direction. v t

, 'l"o couple the pipes A A ltogether at their adjacent ends and to forni a jOintwhiclt-.will provide for the double adjustment of t e pipes, as just speeiiied, and yet keep tightas' against leakagqthe ehainbered portion d of the pipo A has an external screw-thread e its innerend with then'ozzle'or pipeA. b'yajoint ,Ventioin and providing for, the longitudinal cut n'pon.- it and a, beveled orv concave seat j' mede'infits'face end, end the other pipe A has loosely slipped over it,`back of the iin-nge ,ci e, (lished washer g, adapted to t the seatf, and in rear of this again the pipe A has applied to or wound around it a pecking h of iibrous material, preferably asbestns in tape ce form.' 4This packing h and the packing ringr its seat f and arranging the pipes A A 4so that the iieinge c of the pipe A stops short of the back of the chamber d, a tight joint is secured for the meeting end portions of the pipes, both .peripherelly end endwise, with freedom for the pipes 'no expend. or contract or to he turned exially,es desiree.

Having .thus described my invention;

eenen claim es new and desire to seeme'hy Letters Paenty ln a, pipefjoint, the engaging end of the one pipe constructed with en enlarged chamber having a screw-thread on its peripheral exterior and e conceve'seat on its face end, in combination with the engaging end ofthe adjacent pipe, constructed with en outer fiange adapted to freely iitwihin said ehember, a Washer encircling the' flanged pipe back of the Harige and adapted. 'to iit the concer@ seet in the face end of the C hamberetl porction of' the adjacent ipetihii'packing hack of said washer, and e nut inclosing the washer and fibrous packing and having ven internal screw-thread adapted to engage with the' exterior screwthreed on the chambeied portion of the adjacent pipe, also having en inner back lenge constructed to hug .the flanged pipe in rear of the paekingubstenciaily es show-n and described.
